In my state alone a local transmission operator has just given up the ghost on siting a HV line from the southern part of the state to the northeastern part, which would help alleviate some of the bottleneck in the Great Lakes regional grid power flows. They worked for 10 years on it. The NIMBYs crawled out of the woodwork on that one, raising issues from killing trees to affecting the lifestyle of the Amish in the northern part of the state.
We share a state! I recall a transmission line project that was proposed in the 1970's but was stopped by court action in the 1980's - it was a north-south route into the Cleveland area that, had it been built, would likely have prevented the blackout of August, 2003. One of the reasons for cancellation cited in the court hearing was the cancellation of a second generating unit at the Perry Nuclear Power Plant.
There is a definite need for either more south-north transmission in Ohio, or more generating capacity along lake Erie. There are other major population areas with similar problems, of course.
